The industrial PC controlled CETATEST 525 with 7 color touch screen and dual jog dial is a fully automatic leak tester for the detection of leaking parts within the cycle time of the production process. The differential pressure method is used here. This is based on comparing the pressures in the test part volume and in a leak-tight reference volume.
 
The use of fast-switching solenoid valves in combination with a very small internal measuring circuit volume makes the CETATEST 525 particularly suitable for very short test processes.
 
The CETATEST 525 is available in two different types:
The type “pressure decay measurement PD” can be used for leak tests of very small test parts in high speed production. The configuration “sealed components - high resolution SC HR” can be used for test parts which cannot be filled, so called “sealed components”. It is possible to detect very small ratios of test part volumes (0.03 ml < ΔV < 1.0 ml).
 
More than one million measurement results can be stored in the test device and over 256 individually parameterisable test programs with alphanumeric designation are available.
